Hmm but CMW touch is version is 5.8.1.3 not 5.0.2.7 R2 (this still old CMW but in beta phase). Hmm maybe that the faulty one, I'm using 5.0.2.8 which compiled by temasek here maybe you can try these build. If still not work then flash CMW 5.0.2.0 from rom manager.
[LG Optimus 2x] vadonka:
only the incall and the battery low profile required
[LG Optimus 2x] Cydras:
I flashed the CWM 5.0.2.8 by Temasek and the installation doesn't work.

I downloaded the Kernel 1205060954-ETaNa_STOCK_OTF-3.0.y.zip again, and it hangs always in trying to reinit partition. I waited about 10minutes again and then i pulled out the battery.

My phone boots up with Kernel from 3May.

Now i try with CWM 5.0.2.0...
[LG Optimus 2x] vadonka:
the reinit partition code is running before the kernel installation, so if you have a hang while that process, its some kind of partition problem or the CWM version issue.
[LG Optimus 2x] Cydras:
I tried CWM 5.0.2.0 and it doesn't work.

What can i do?
[LG Optimus 2x] IDan1109:
Just a question. What DS battery driver means? Because i see that sometimes i have 86% of battery then after a minute 88%

[LG Optimus 2x] afpapa:
I tested over the weekend the beta version (OC) and had two times BSOD (not on charging, there I had no problem). On the same time the battery went crazy, from 80% to 40% in minutes. I reverted to stock kernel for now, as I need the phone to work (for my work). I'll try again next weekend.
[LG Optimus 2x] Cydras:
It's a batery driver with funky battery reading, but the battery life is higher.

Because that, on the battery indicator can not be trusted.

I think DS was Debauched Slot or something.
[LG Optimus 2x] alakyr:
ok thank you =)
[LG Optimus 2x] reginickneo:
The funky reading is because of the driver based on real time battery consumption. If you make a phone call or play games it goes down really fast, and after that it "charge" itself.
[LG Optimus 2x] IDan1109:
So is it trustable? i saw that.. when i use 3g it slow down fast.. then charge as you said.. so have i to trust battery after it "charge"?
[LG Optimus 2x] powwow88:
I never used DS battrey but as i read here before, when it "charged back" it will show the correct value.

a bit off: LG delayed the ICS update to Q3.:mad:
[LG Optimus 2x] reginickneo:
The only problem it that it can switch of itself faster is you do something which drains the battery heavy. But it will show higher amount of power remaining after a while. 3G is also critical because on O2X it eats your battery.

I used for a very long time the DS driver, I ussually use facebook and opera on wifi, or some games and it was able to give me 5 hours of screen / day, but there are some inconviniences. The indicator shows you that if you do the same you will have xy% left, that is why it could go down really fast with 3G/phone calls/games which needs a lot of power or CPU use (the driver is based on real time energy consumption).

Normal driver is about 3,5 hours of screen for me.

Sry for my English.

edit:

"a bit off: LG delayed the ICS update to Q3."

**** happens. It would be enough for the developers if the nvidia released the source code. HW acceleration cannot be solved without it.
[LG Optimus 2x] elvnox:
Hello thank you for your work, but with the new kernel i have very high battery drain! The kernel 27.4 doesn't have drain...

[LG Optimus 2x] kennbo82:
Seems any bigger issue with your partitions?

For me, if any big problem, it helps to use SMARTFLASH to reset everythin on phone to standard. Then install custom rom and kernel again.

You tried this already?
[LG Optimus 2x] buedi:
Hello Vadonka/*,

so far the best release ever (6th May) - thanks for the hard work. Great response, no BSOD yet (after 16h of uasge (yes not long enough to give a final feedback, but I had 1-2 a day in MIUI). Battery still "draining"/worse like always - not better in relation to older releases (I think the typical 3G drain).

Greetings
[LG Optimus 2x] Cydras:
I haven't tried this. I'll try it out later.

Thanks.
[LG Optimus 2x] tonyp:
Is it possible to include more gouvenours like smartassv2?

Or doesn't the phone like that?
[LG Optimus 2x] Cydras:
I found out that i can no more copy data to the sd card.

Check Disk on Windows crash.

I put in another sd card and same problem.

In CWM i can't make Backups.

Can i make with no risk a reset with Smartflash with the kdz files?
[LG Optimus 2x] hadi_rena:
Back Up your SD card content to computer

Full Format it (Windows user please DON'T check quick format)

Check Disk again (should be error free and no bad sector)

Make sure all sector are writable (copy any file to your SD till full / reaching 0 byte free)

If your SD is NOT fully writable then use another SD and repeat from step 1

empty the SD card and attach to phone

perform CMW backup

Install Kernel

If problem persist maybe something problem with your phone

Hope help
[LG Optimus 2x] kennbo82:
Afaik this is hardcoded in Nvidia Tegra and cannot be changed, means our phone ignores any other governor setting.
[LG Optimus 2x] antec123:
are you still expecting LG to launch the ICS for next update?? i would prefer CM9 unfortunately there is no driver tegra2 for our beloved phone yet :(

unfortunately no. i think there is already been discussed somewhere in the development section.
[LG Optimus 2x] razerblade17:
hey guys...can u suggest me which apps is good for oc and uv? and can u help me to get better setting for better battery performance...
[LG Optimus 2x] redh4t:
Which kernel have better battery life? 2.6 stable or 3.0.30?
[LG Optimus 2x] razerblade17:
for me kernel 2.x.x
[LG Optimus 2x] @dap:
TrymHansen wrote a nice app for controlling OC and other parameters:

http://xdaforums.com/showpost.php?p=25141471&postcount=1

For UV and other parameters you can download the ETaNa kernel tweaker app for free from the Google Play store...
[LG Optimus 2x] razerblade17:
thanks..can u give me setting for better bettery performance?
[LG Optimus 2x] CVonV:
i used to use this kernel but it was too unstable with some games.. in particular, Draw Something.

Can someone please report if this is still the case with said game?
[LG Optimus 2x] antec123:
yes, draw something is incompatible with this kernel, try use CM stock kernel..
[LG Optimus 2x] slebit:
I can confirm that. But sometimes it is working for me, but most of the time it just force close in the start.
[LG Optimus 2x] powwow88:
I would prefer CM9 as well (with a Vandonka's CM9 kernel, if he's gonna work on it) but till no official LG ICS there won't be fully working CM9 cuz it seems Nvidia won't release drivers/source code. Anyway, no issues with 120406 kernel so far.:)
[LG Optimus 2x] ppino:
Similar problem here with the stock DS kernel.

Two bsod and huge battery drain, going to 0.

I charged completely and kept using.

Sent from an awesome O2X thanks to you all.
[LG Optimus 2x] PAIIITET:
Tell me, who can come across.

While charging the phone periodically loses mobile connection, and the battery is frozen. can not call.

changed the BB 824, 20120313, used different ril, nothing helps.

First there was the kernel 2.6.x ethane, now 3.0.30

blame if the kernel etana?

LG Optimus 2Χ [16Gb MicroSD Plus Extreme Speed Class 20]

[LG Optimus 2x] Cydras:
Thanks, i can write on my sd card, but i can't make a backup with CWM...

I had to take out the battery.

The only way to solve this problem is smartflash or?
[LG Optimus 2x] kennbo82:
I guess if you want to format /system with CWM (at "mounts and storage"), you get the error message that CWM cannot mount it? Be careful, if you want to test it, you need a custom rom on your SD Card for flashing it again after in case the format works ^^.

I just tell that I had this mount problem, was not able to backup something with CWM because of it, but I didn't want to play with ADB shell so I used Smartflash and the problem was solved (yes, i told in earlier posts already). But Smartflash put everything to standard (except your SD Card), so best you have app backups with "Titanium Backup" (for example) for easy recovery.
[LG Optimus 2x] vadonka:
New beta version is uploaded.

Im a bit tired so full changelog tomorrow (there is many many improvements in there)

but i can tell you one thing:

- Draw something is fixed :cool:

edit:

surprise, plants vs zombies is now working too :)

Download from here
[LG Optimus 2x] jay_snake:
Even with the OC versions?
[LG Optimus 2x] Cydras:
Thanks!!!! After i format the system i installed my rom again and now the reinit script has worked!! The Kernel is installed and all works :D
[LG Optimus 2x] vadonka:
yes, i also used the oc version and i played with draw something for a 10 minutes and no freeze or any issue :)
[LG Optimus 2x] slebit:
Awesome! Will try!
[LG Optimus 2x] vadonka:
well there are many good cm9 kernel out there already :)

i dont want to work on the cm9 till the lg not released the cm9 official.

actually i was joined some other developement project (not kernel) recently, so i need heavy multitasking :)

i stick with the cm7 kernels for now. almost every developer working on the cm9 kernel, for the cm7 only a few exsist and the most maintained is...well... :)
[LG Optimus 2x] ppino:
Just flash new beta and only can say... AWESOME!!!:D

Very, very smooth.

My phone was lately a little bit laggy (transitions between desktop or scrolling a conversation on whatsapp) and now it's again like a rocket.

Thank you Vadonka, you rules.

Sent from an awesome O2X thanks to you all.
[LG Optimus 2x] temasek:
None other than .....

Uuuuuuuuuuuuuuu :D
[LG Optimus 2x] hadi_rena:
:eek: a big surprise !!! that game now working on this kernel ??? what have you done vadonka ?? I really thankful that you and temasek working really hard for O2X so I didn't think to move to other device :D

Will try for draw something first... if found any problem I'll report it later
[LG Optimus 2x] silentmelodies:
Wow, draw something does indeed work now. Performance also seems to be smoother.

Great job Vadonka :)
[LG Optimus 2x] tonyp:
Interesting, the CPU meter app shows me more/different steps than the 8 "slots" from the kernel.

Like 245.48 (or something like that). I always thought that we're limited to the steps you set into the kernel, are we not?
[LG Optimus 2x] brudy:
Hi Vadonka!

I'm using the lateset beta kernel (1205060958-ETaNa_OC_OTF-3.0.y.zip). When the phone is screen off state, the WIFI is not go to sleep. Always connected, when I press the phone's power button. Everything else are works perfectly.

THX your hard work.
[LG Optimus 2x] vadonka:
this is depending on a rom option. you set this up from the wifi screen press the menu button then pick the advanced menu.

i also use this option: wifi sleep when screen is off

and its working without any problem
[LG Optimus 2x] Cydras:
Hi,

i flashed your Beta and all runs amazing smooth! No lags!

Thanks Vadonka! :)
[LG Optimus 2x] vadonka:
Beta kernel changelog updated in the second OP post.
[LG Optimus 2x] reginickneo:
Gonna try it out!:) Waiting for being fully charged.
[LG Optimus 2x] brudy:
I'm on this option (wifi sleep when screen is off). Maybe Temasek's Kang 100 is the guilty? :-)

Other feedback: I'm tried to pick up an incoming call, but the phone was freezed and shot down. The logger was disabled, but I turning it on now.

I'm using your kernel since the beggining, and I love so much your kernel, and I try to help your work a little.
[LG Optimus 2x] slebit:
I have to say that after I have been using cm9 that cm7 with etana kernel is so fast! No lags what so ever! Thanks a lot!
[LG Optimus 2x] powwow88:
For me incoming and outgoing calls work well with latest beta kernel. :)

[LG Optimus 2x] vadonka:
the in/out calls issue only occured with the v21y nvrm daemon binary, but im revert back to the v20q what is working fine long time ago.

so the in/out calls should be fine.

i also experienced massive battery life improvements
[LG Optimus 2x] DeepEmbrace:
Hey Vadonka, thanks for the awesome kernel :)

While im flashing ya latest beta, just gonna ask a question. What was the deal with draw something and P vs Z?

Me being a noob app dev, its making me curious. Does the app call something specific that differs with kernels? So in theory it could freeze up with stock roms from any store bought phone since some manufacturers customise their kernel?

Cheers :)
[LG Optimus 2x] vadonka:
actually i was complicated the things too much :)

i try to find the issue in the kernel sources, but the problem is much more simple

just a few missing kconfig option needed like some extra errata workaround, and need to disable the swp emulation.

the root of the problem is that the application try to gain a permission from the system an unusual way and (because the kernel process management) this was prevented, in that case the program main window is crash, what is mean: freezed, dropped out the desktop, etc.. now the permission is granted successfully and this apps is working too now.

i can say now, im not have any remaining issue, my phone is fast, stable and have a good battery life.

but i also need your feedback guys :)
[LG Optimus 2x] DeepEmbrace:
Ah cool, that makes sense :) Thats always the issue with programming :P

I have flashed your beta and will report back in 2 days after some hardcore usage :)
[LG Optimus 2x] vadonka:
okay, make some heavy test :)

When I go back to the latest stable etana kernel, the wifi always on problem is gone. Any idea?

bumbee too finally!!!! what was the problem?!

Here's Vadonka's answer to that a few posts back. :-)
[LG Optimus 2x] alakyr:
lol i forgot it xD
[LG Optimus 2x] Sörnäinen:
The latest version gives me BSOD quite often - three times in the last two hours.

Also instagram stopped working, but well ... maybe I can live with that. :)
[LG Optimus 2x] alakyr:
this is only a good thing xD
[LG Optimus 2x] umirza85:
Vadonka the beta is amazing, my phone has never felt smoother. And draw something works better and smoother than even on my tablet. Using the stock (beta) with temasek's 100 build and im so incredibly happy with my phone. Thank you for your hard work.
[LG Optimus 2x] vadonka:
Referred to the phone hardware there is a possibility that the phone turn himself off under heavy load while on an USB charger. Its not a kernel or a ROM issue.

This is happen rarely when you playing some heavy games what is have strong resource requirements. In that case the USB power cant compensate the phone power consumption then its turned off for safety reason.

Unexpected poweroff also occured when you used too strong undervolting.
[LG Optimus 2x] Sörnäinen:
Thanks for the hint - it didn't happen on the charger, just when the phone was on the table.

I didn't undervolt, just used your standard settings. Sounds as if I should lift them a bit? How much should I add, can someone give me a bit advise? I can do that in the etana tool app, right?
[LG Optimus 2x] IntenseColor:
Am I the only one encountering a very slow SD card write speed in the 3.0.y versions?

I think I had this problem from the beginning of the 3.0.y versions.

The speeds I am getting is below 700 KB/s. With the latest 2.6.32.y I get a much faster speed of more than 5 MB/s.

Did I maybe do something wrong?

I just fully wiped, reinstalled CM7.2 and installed a different baseband. And it didn't make any difference.
[LG Optimus 2x] Rayman96:
Try to wipe dalvik cache and remount your sdcard in system :)
[LG Optimus 2x] nebregg:
Nice to see Vadonka that Draw Something is fixed! :)
[LG Optimus 2x] vadonka:
Wifi sleep is working.

But!

The wifi sleep mode is a bit chaotic, sometimes it takes 10-15 min before the wifi goes to sleep mode. Maybe checking the network traffic and if something using the wifi then not sleep, i dont know. This is controlled by the ROM actually.

I strongly recommend to use this app: https://play.google.com/store/apps/details?id=com.lastmile.wifitimeout

its free and very simple, you can set the timeout value. after your screen is off the wifi is disabled too after this time value. if the screen is on again the wifi is enabled again. you can set even 1 second timeout if you want.
[LG Optimus 2x] vadonka:
its fixed already

my class10 samsung sdhc card have 10MB/s writing and 20mb/s reading speed.

through USB around 8-10MB/s reading speed, but its because the poor usb2.0
[LG Optimus 2x] IntenseColor:
Thanks for answering but I have tried wiping the dalvik cache many times and it did not work.

And how do I remount my SD card in "system"? I have tried unmounting and mounting the SD card in Settings->Storage. But still no dice.

I don't think it's my USB cable or USB port in my laptop. If I downgrade to the 2.6 version of the kernel the write speed is much faster right away.

If I do a SD card read/write benchmark on my phone I get good results (~9 MB/s write and ~20 MB/s read).

Though I did find something suspicious when flashing the kernel. Each time I flash to the latest 3.0.y kernel it says that I have to "rebuild" (not sure if this is the right word) /system.

Does it have something to do with that?
[LG Optimus 2x] :
great, thanks Vadonka. Together with this:

https://play.google.com/store/apps/details?id=rubberbibpepper.WiFiTxPower

we're getting closer to "charge once, use forever" :)
[LG Optimus 2x] tonyp:
Looks interesting, could you tell your experiences? Do you notice a longer lasting battery when on wifi for sure?

And do we have to adb push iwconfig for the 2x?
[LG Optimus 2x] vadonka:
im using the wifi txpower app tx power set to 11dBm and the wifi timeout app with 30 second. its save valuable battery life :)
[LG Optimus 2x] tonyp:
I kept researching about TXpower and found this:

Won't use it then I guess.
[LG Optimus 2x] vadonka:
not exactly

in the bcm4329 module the tx power defines the transmit power in dBm. this is used for the in and out transmit too. i search for this already in the sources, find the default tx power too.
[LG Optimus 2x] tonyp:
I do trust you on this then :)

Just wanted to point this post out as it might have been true.

Low Memory Killer value

Hi guys I have a question related to Low Memory Killer (LMK) in etana tweakaio. Default value for LMK is str (strict) and I have around 100 or more MB memory free with 48 MB ram hack. Then I changed LMK to extr (extreme) and have around 200 MB memory free. AFAIK in android better we have 'little' memory free because apps are cached in memory for faster performance and responsiveness (CMIIW).

Now my question is what is the most appropriate value for LMK with 48 ramhack so we can gain the best app performance and system still responsive ? I try auto value and auto value give same settings with strict. It'll really nice if someone can post link about LMK so I can read further (please note I'm not a linux master :D)

Thank You
[LG Optimus 2x] :
Well, I surely didn't know all of this. :D But I do notice the better battery life (@4 dB). Only the last few weeks I had a drain by wifi keeping my device alive... Hopefully the timeout can help there.

Thanks for the discussion guys!
[LG Optimus 2x] vadonka:
BETA version updated to v1.0-1-g053435
[LG Optimus 2x] alakyr:
downloading ;)
[LG Optimus 2x] vadonka:
Plants vs Zombies issue:

- if you using ramhack greater than 32MB then you will have some texture problem in this game (black textures), you can avoid that with chainfire 3d reducing the texture depth to 16 bit, bit it will broke some other textures in the game. so its not a perfect workaround.

this is not a kernel issue, it seems that game using a lot GPU memory. using 32MB ramhack doesn't cause this issue, the first appear when you used the 48MB or above.
[LG Optimus 2x] xtrustkillx:
No, same problem here. Internal and external.
[LG Optimus 2x] vadonka:
what is slow? internal copy or via USB?
[LG Optimus 2x] xtrustkillx:

[LG Optimus 2x] 4lph4:
I'm always surprised by the amount of tweak and improvement you are doing on this kernel.

I just find the time to post and say the beta version from 7-may had an excellent battery life (also on 3g) and I find there is already an update :D ... argh I'm always one step behind :eek:

Thank you again Vadonka!
[LG Optimus 2x] vadonka:
please make an internal speed test.

Got a BSOD and badly hot device. Pulled battery and my battery indicator was down to 4 % (from over 50 %) :-( To bad I didn't catch a log since I didn't have a cable.
[LG Optimus 2x] vadonka:
that sound like something is stucked in the memory and utilize the cpu at 100%.

the phone getting hot because the heavy cpu consumption and this drain the battery very fast. i suggest to use the better battery stats app, in that case you can check that what was that stucked process
[LG Optimus 2x] vadonka:
the screen off max freq kernel side limit is activated only when the phone enter the suspend mode, if the phone remain awake just the screen is off the cpu speed not limited, so if you have some buggy app what is eat the whole cpu time your phone become hot soon and the battery is drained fast.

if your phone battery drained fast and/or heated up, mostly not a SOD occured but a simple poweroff. try to hold the power button before you pulled out the battery.

[LG Optimus 2x] vadonka:
my sdcard is a samsung sdhci 32GB class 10 card

sd tools test results is: ~9MB/s write/20MB/s read

and here is the PC<-->USB speed test results

the read speed is slower than in the phone, but the write is close to that.

my notebook USB port is poor so i blame this not the card :)

OS: windows 7 ultimate 64 bit

i format the sdcard with 32768byte allocation size instead of the default 4096byte, but i dont think its related to this.
[LG Optimus 2x] xtrustkillx:
Thanks, maybe its just fragmentation whats slowing it down. Anyway i can live with that:)
[LG Optimus 2x] alakyr:
same card but 16gb version and the sd tool app for android say me 15.1mb/s write and 19.5mb/s read

sometimes when my sdcard get fragmented i was copyed everything to my pc then format the sdcard using a card reader, then copy everything back. after that the speed was much more faster.

[LG Optimus 2x] vadonka:
i remember that is discussed a while ago. it is not possible to adopt our kernel because its need an atmel chip touchscreen.
